PRECAUTIONS DURING INSTALLATION

WARNING

CAUTION

• Do not reconstruct the unit.

Water leakage, fault, short circuit or fire may occur if you reconstruct the

unit by yourself.

• Please ask your sales agent or qualified technician for the installation of your unit.

Water leakage, short circuit or fire may occur if you install the unit by yourself.

• Please use earth line.

Do not place the earth line near water or gas pipes, lightning-conductor, or

the earth line of telephone. Improper installation of earth line may cause

electric shock.

• A circuit breaker should be installed depending on the mounting site of

the unit. Without a circuit breaker, the danger of electric shock exists.

• Do not install the unit near location where there is flammable gas.

The outdoor unit may catch fire if flammable gas leaks around it.

• Please ensure smooth flow of water when installing the drain hose.

PRECAUTIONS DURING SHIFTING OR MAINTENANCE

• Should abnormal situation arise (like burning smell), please stop operating

the unit and turn off the circuit breaker. Contact your agent. Fault, short

circuit or fire may occur if you continue to operate the unit under abnormal

situation.

• Please contact your agent for maintenance.

Improper self maintenance may cause electric shock and fire.

• Please contact your agent if you need to remove and reinstall the unit.

Electric shock or fire may occur if you remove and reinstall the unit yourself improperly.

• Avoid an extended period of direct air flow for your health.

• Do not put objects like thin rods into the panel of blower and suction side because

the high-speed fan inside may cause danger.

• Do not use any conductor as fuse wire, this could cause fatal accident.

• During thunder storm, please stop operating the unit and turn off the circuit breaker.

• The product shall be operated under the manufacturer specification and not for

any other intended use.

• Do not attempt to operate the unit with wet hands. This could cause fatal accident.

• When operating the unit with burning equipment, regularly ventilate the room to

avoid oxygen insufficiency.

• Do not direct the cool air coming out from the air-conditioner panel to face

household heating apparatus as this may affect the working of apparatus such

as the electric kettle, oven etc.

• Please ensure that outdoor mounting frame is always stable, firm and without

defect. If not, the outdoor unit may collapse and cause danger.

• Do not splash or direct water to the body of the unit when cleaning it as this may

cause short circuit.

• Do not use any aerosol or hair sprays near the indoor unit. This chemical can

adhere on heat exchanger fin and blocked the evaporation water flow to drain

pan. The water will drop on tangential fan and cause water splashing out from

indoor unit.

• Please switch off the unit and turn off the circuit breaker during cleaning, the high-

speed fan inside the unit may cause danger.

• Turn off the circuit breaker if the unit is not to be operated for a long period.

• Do not climb on the outdoor unit or put objects on it.

• Do not water container (like vase) on the indoor unit to avoid water dripping onto

the unit. Dripping water will damage the insulator inside the unit and causes short-

circuit.

• Do not place plants directly under the air flow as it is bad for the plants.

• When operating the unit with the door and windows opened, (the room humidity is always

above 80%) and with the air deflector facing down or moving automatically for a long period of

time, water will condense on the air deflector and drips down occasionally. This will wet your

furniture. Therefore, do not operate under such condition for a long time.

• If the amount of heat in the room is above the cooling or heating capability of the unit (for

example: more people entering the room, using heating equipments and etc.), the preset room

temperature cannot be achieved.
